THlLL-COUPLING.

SPEOIFICATIQN'forming part of Letters Patent No. 423,892,dated March 181890. Application filed October 12, 1889- Serial in. 325,724. on man.

To all whom it may concern.-

Be it known that I, EUGENE M. HownN- s'rEIN, a citizen of the UnitedStates, and a resident of. Nappanee, and State of Indiana, have inventedcertain new and usefullmprovements in Shaft-Coup- 'lings; and-I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to y hich'itappertains to make and use the sameg'reference being had to theaccompanying' drawings, andto letters of reference marked thereon, whichform a part of this specification.

c Figure 1 of the drawings is a representation of this invention and isa top view. Fig. 2 is a side View, Figs. 3, 4:, and 5 are perspectiveviews of different parts.

This invention has relation to means for coupling shafts and poles tovehicles; and it consists in the novel construction and combination ofdevices, all as hereinafter set forth.

In the/accompanying drawings, illustrating this invention, the letterA'designates an arm connected to the attachment-plate B, andcarrying atits upper end the transverse-conical end bearings 0. Usually the arm Aand bean.

ing 0 are made integral with the plate B, which. is preferably theclip-plate, and is secured to the axle by the clip-band E.

The end ofthe shaft or pole arm is indicated at F. It is formedwith aconical socket G, opening inward to engage one of the covered ends 0 ofthe bearing C. It is also found with a catch recess or shoulder at H,adapted to receive and engage a projection or catch K of the section F,which is provided at its rear end also with a'conical socket G,openinginward or toward the socket G to engage the other conical end ofthe transverse bearing 0. An opening Z, usually square, is made throughthe part F of the shaft or pole arm, and an ijn'the county of Elkhart'opening Z through the socket-carrying section F'- to provide bearingsfor the tensionbolt Z, having the nut z. When the parts F and F aretightened against the conical ends of the bearing 0 by means of the bolt01 tension device, the sockets are brought closely up against said endsand the coupling will not 'sh'ake'or rattle. Should it move loose, itcan be tightened in a few moments by turning the nut on'thetension-bolt. The shoulder H and catch K of the part F andsection F aredesigned to afford strength to these parts, especially in the forwardand backward movements of the shaftsor ole.

Having described t is invention, what I claim, and desire to' secure byLetters Patent, 1s

The shaft or 1 pole coupling consisting of theclip-plate having theoifset, vertical arm,-

- providedwith the transverse conical end bearing, the shaft or polesection provided atone end with a conical socket which receives one endof said transverse bearing and inward from said socket, with a recess H,the shoulder formed by one wall of which stands somedistance inward fromthe inner side of said polesection,'the shaft-coupling section providedat one end with a conical socket, which rerceives the oppositeend ofsaid transverse bearing and at its inner end with acatch or hook, whichengages said recess and shoulder and stands at its inner end in theplane of said shaft or pole section, and the bolt passing through saidpole and coupling sections and spanning the space between the latter,substantially as specified.

. In testimony whereof I affix my signature in presence of twowitnesses.
